At 759 torr, 0.002 86 g of the gas will dissolve.
Henry’s law states:
, where
where is a proportionality constant called the Henry's Law constant.
If we have the same solute in the same solvent at two different pressures and
,
and
Dividing the two equations, k_H cancels and we get
c_1/c_2 = p_1/p_2
<em>c</em>_2 = <em>c</em>_1 × <em>p</em>_2/<em>p</em>_1
The volumes of solvent are the same, so we can use the masses of the solute instead of concentrations.
∴ <em>c</em>_2 = 0.003 27 g × (759 torr/867 torr) = 0.002 86 g
